Solvent Dyeing
Solvent dyeing is a dyeing procedure completed from a persistent non-acqueous stage. Here Solvent is utilized as dyeing media. In any case, water may be added to support coloring methodology. Since the presentation of hydrophobic filaments like cellulose acetic acid derivation in 1920's Solvent have been considered for coloring in light of the fact that it was impractical to color such strands with ionic colors and water. 
The particles of solvent dyes are non-polar (or have a little measure of extremity). This implies that the diminishing methodology does not occur through ionization (similar to the case with different sorts of colorants like acid dyes). Consequently, solvent dyes are regularly insoluble in water.

Solvent dyes are genuinely flexible and utilized as a part of different applications. One kind of non-polar, natural solvent that is usually utilized with solvent dyes is petrol. Accordingly, solvent dyes are frequently utilized as a part of the auto industry to color petrol fuel and other hydrocarbon based fuel oils. They are likewise usually used to color candles and waxes, ink and inkjets, wood stains and coatings, and an assortment of other non-polar, hydrocarbon based materials. In view of their synthetic similarity, solvent dyes have gotten to be broadly utilized for dyeing plastics. The coloring of PVC is currently done completely with the utilization of solvent dyes.

The naming of solvent dyes has been institutionalized, after the example of the color of the dye (and a recognizing number) nearing after "solvent" for instance, numerous shades of red solvent dyes are separated by the number toward the end of the name (i.e. "Solvent Red 1," Solvent Red 49," Solvent Red 24," Solvent Red 111," etcetera).

Solvent dyes are only one sort of colorant that Pylam offers. Whatever your item may be, we are sure to have the fitting dye or color. The majority of our colorants, including our solvent dyes, are of the most astounding quality. We direct exhaustive testing to guarantee that the colorants we pick coordinate the concoction creation of your item. Contact us today and let us help you locate the ideal color for your item.

Qualities of Solvents: 

A perfect solvent for Textile transforming ought to have the accompanying attributes – 

1. Non- lethal. 

2. Non-combustible. 

3. Non-destructive. 

4. Latent to material materials. 

5. Stable to rehashed refining. 

6. Low Specific warmth. 

7. Low warmth of vanishing. 

8. Promptly accessible. 

9. Monetary attainabilit

The types of Solvent Used in Textile Processing: 

A few solvents of chlorinated hydrocarbons of aliphatic arrangement forces a large portion of the said prerequisites and consequently are being utilized as solvents are widely utilized, for example, –

1. Tri-chloro Ethylen (TCE).

2. Every chloro Ethylen (PCE).

3. Methyl Chloroform (MC).

Each of the three solvents are similarly suitable yet tri-chloroethylene has high strength to decay and thus isomers ideal.

Favorable circumstances of Solvent Dyeing:

1. High wettability and dyeability.

2. Fast coloring with least vitality necessities.

3. Better levelness and color yield contrasted and better fabric feel.

4. Solvent Dyeing is being reused, so the gushing control issue is wiped out.

5.Less time needed.

Impediments of Solvent Dyeing:

1. Solvents are lavish, so higher generation cost.

2. Issue in supplies accessibility.

3. Existing color can not be utilized as a part of full rang.
